Try the adult sector... file upload sites are very popular and with a bit of promotion you should be able to build a lot of traffic. There are a ton of adult links directories to submit to, and many forums to post on. Often, once you are known the word will spread itself as well.

Advertising wise you'd need something catering to an adult audience but there are many adult affiliate schemes you can try...

Figure out who exactly you want to appeal your site to. From there, figure out what types of sites those people visit. Find some sites, find out info on the owners, find what forums they're part of, develop a relationship with those owners, and begin getting traffic.
